DEX policies for macOS

Policies for macOS are guidelines and rules to promote that the application is used in a consistent, secure, and conforming manner. DEX policies your organization to reduce the risk of data breaches, improve data quality and accuracy, and optimize application performance and availability.

For macOS systems, to retrieve the entire data, include the subsequent content to /private/etc/sudoers.d/_servicenow.

Note:

The historical data for an application or device is the information that is kept in the MetricBase database for the past 7 days, while the latest data pertains to the most recent information available.

Policies for Mac — Application

DEX provides the following policies for applications.

Policy name	Description	Check instances	Frequency	Historical or latest	Check instance parameters
